2. 11. An Experimental Study to Understand the Localized Corrosion and Environment-Assisted Cracking Behavior of AISI 420-Martensitic Stainless Steel

   Author : Krishnan Hariramabadran Anantha; Jinshan Pan; Robert Akid; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kemi; Chemistry;

   Abstract : Motivation and aim: Currently steel molds are designed with cooling channels to reduce the solidification time of molten plastic within the mold to improve the productivity. As water is generally used as the cooling medium, corrosion and environment-assisted cracking (EAC) leading towards the dysfunction of mold, can increase the production downtime. READ MORE

4. 12. Very high cycle fatigue of tool steels

   Author : Vitaliy Kazymyrovych; Jens Bergström; Arne Melander; Karlstads universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fatigue; crack growth; ultrasonic testing; tool steels; inclusions; Materialteknik; Materials Engineering;

   Abstract : An increasing number of engineering components are expected to have fatigue life in the range of 107 - 1010 load cycles. Some examples of such components are found in airplanes, automobiles and high speed trains. READ MORE

5. 13. Life assessment from weld microstructures at high temperatures

   Author : Jan Storesund; KTH; []
   Keywords : ;

   Abstract : Most pressure vessels in fossil power plant are designed forcreep. After operation of the order of the design lifetime thematerial may be degraded and further operation is limited.Methods which can prolong the lifetime and assess thecomponents is therefore demanded. READ MORE
